A hot tub with a surface area of 30 ft2 is filled with water to a depth of 50 in. Hint: volume is calculated as area · height.
Remember, cm3 = ml and cm2 x cm = cm3
Do not panic, this is just a unit conversion problem. Please show all work.
a) What is the volume, in liters, of water in the tub?
b) What is the mass, in kilograms, of water the hot tub contains?
c) How many kilocalories are needed to heat the water in the hot tubfrom 62°F to 105°F?
d) If the hot tub heater provides 5900 kJ/minute, how long in hours, will it take to heat the water in the hot tub from 62°F to 105°F?
